Probably the best story out of the 3, with some actual plot going on. The story isn't that great itself but I still liked it. Seeing the title I guess you know what it's about. I liked the characters, especially Mugi, determined to achieve anything at the right time.
This story was pretty refreshing. Although it's the shortest story out of the 3, it presented a lot about the contrast between the calm library and the busy city. Decent.
Now this one was odd. It's either because I didn't really get the story or the story's just bad. Some scenes were inexplicable for me
and I didn't really understand the female lead's goals. Some of the dialogue was appealing to some extent, but that was about it. Don't know why they included sexual acts in this story... The ending was probably the only good thing.
The art was very good. Ir reminded me of Taifuu no Noruda's art a lot. Simple yet the small details stand out. You could say it's cute as well.
I enjoyed the first 2 stories, but not the 3rd one, since I was left a bit confused. Overall a 7.
